The invention generally has for its -;object to provide novel means for separating and covering bulk cement or the like when being transportedin batch association With sandand gravel or similar materials and priing and separating meansin' the nature ofa plurality of flexible sheets secured along one edge only to the truck body ina manner;

enabling them to be lappeddovvn :into the body in-varying degrees to cover thecement and separate from the sand, and permit ting free discharge of the batch-Without the necessity ofmanipulatingthe sheets or any 'portionthereof. This free edge construction provides'for the eflicient covering and separation of the cement, and also provides a desirable flexible means capable ofibeing readily collapsed against the truck Walls" when not in actual use, but the open sides of the siiperposed sheets make is necessary in loading to first fill the cement into a confining form placed over the separating sheet and then to slowly remove the form to avoid splashing'of the cement off into free space due to the fast pouring thereof. The present invention therefore seeks-to providea novel cement receiving envelope iwhich embodies all of the advantages offie'xibility, and efiiciency of covering and separating the cement which are present in'my previously disclosed means but which in addition assures against side splashing duringloading, thereby speeding up the loading action and avoiding lossesdue 'to the Waste incident to such splashing and also thoseioccajsioned byreason of the necessity of providing special loading forms or the'like'i V In its more detailed nature theinvention resides in the provision in a cement, sand and gravel batch transporting triic'k dump and relatively shallow. envelope of a size for outof theenvelope.

,In the drawings I have shown so much of atruck and its dump body as is necessary :to illustrate the application of the invention. The invention is mountable on any conventional form of such truck and since the body elevating or dump effecting mechanismforms no part of the invention it is not shown.

' ,ing compartments'and the said members 9 are swingably mounted on the body side walls "as at 10.. In this particular disclosure the members 9 are shown as normally seated in floor seats 11 and when it is desired to dump ;a batch, the body 6 first having been raised on its pivot 5, it is only necessary to manipulate the respective handle or crank 12 to cause the eccentric hub 13 in which the pivot shaft 110 is secured to engage the top face of the body side and elevate the member 9 out of I the seat 11 to enable it to swing on the said shaft 10.

I The parts thus far described are all conventional and their detailed construction and manner of operation is well understood to 7 ,may be, elevated as indicated in Figure 6, the

workers in the art. Theinvention resides in combining with theseparts the novel flexible "cement covering and separating envelope which I am about to describe.

In order to facilitate an understanding of the details of construction of the envelope, I have illustrated in Figure 5 of the drawings a blankfrom which the envelope may", be ---formed. AIt is. to be'understood, however, that the invention comprehends the construc tion of-the envelopesboth from blank form and by fabrication from suitably cut and assembled individual pieces as may be desired. The material is preferably waterproofed canvas but any other suitable flexible material may be employed.

The envelope, constructed from blank form or by fabrication from suitable pieces, includes bottom and top body faces 14 and 15 of like size, front and rear walls 16 and 17 of like size, and side walls 18 also of like size. The top body face is extended to provide an overlap 19, the front wall 1'6 is similarly extended to provide a cooperating underlap 20, and

" each side wall 18 carries an L-shaped corner extension 21, the purpose of all of which will become evident as the description progresses. See Figure 5.

. ,The various parts of the envelope referred to in detail hereinbefore are secured together by sewing or otherwise to provide therelatively shallow flexible envelope shown. in

Figures 2,8 and 1-. The adjacent edges of the walls 16. and 1 8 however. are not secured.

together and hencethere is provided an open mouth for the bag which is closable by the front wall 16 aided by the flaps'20, 19 and 21. L

It will also be observed that the top bodyface 15 is joined to the side walls 18 through a portion only of their length, they being secured 7 only to a point approximating the positions of the L-shaped flaps 21, thus providing for an enlarged filler throatway, greater; freedom of the flap 19, and also for the provision of said L-shaped flaps.

Mounting straps 22 are secured at 23 to the rear wall 17 and have their free ends provided with grommets 2a to facilitate adjustable connection at 25with the respective batch divider wall 9.

Flap securing straps 26 may be provided if found desirable. cured at 27 to the front wall 16 so that'the free ends of the straps may cooperate with the buckles 28 secured at 29 tothe top body face 15 for securing the envelope with the cement encased therein;

The mounting straps 22 serve to secure the envelope to the batch dividers in a, manner enabling dumping of the cement out through the open throatway without removal of the envelope from its mounting, the connection being flexible enough however to greatly facilitate filling as indicated in Figure 6.

r In filling, the open throat of the envelope the envelope is closed as indicated in Figures .3 and 4 the cement within the enclosure exerts These straps may be se-;

a pressure outward against the flaps 21, 20

and 19, inthe order stated, forcing them into tight contact and causing them to effectually seal the envelopeopening against egress of cement. The istraps .26 serve to assure against displacement'ofthe flaps but it is possible to relysolely upon the engagement of the flaps to seal the opening or to "so position the envelope that the divider wall 9 adja- "cent the envelope opening will serve to hold the front wall 16 againstopening movement. See Figure 10. I l In' Figures 7,8'and 9'of the-drawings I have disclosed a preferred means for securing' the-flaps while in transit. In this connection- Iemploy the well known spot fasteners which are snap fasteners separable by a pull exerted at one point only, indicated by a spot on the female part of the fastener. I somount thesefasteners on my flaps that they will be automatically separated by the "pull occasioned by the weight of the cement Y tending to force the flaps apart during dumping of the truck. l I The male fastener members 30 are secured to the flap 20 to projectin the manner indi-.

cated" in Figure 7, and the female fastener members 31 are secured to the flap 19in position to receive the male members as indicated in Figures (and 8. v vr In Figure 9 of the drawings I have shown one of the female snap members 31 in detail, the spot 32 serving to indicate the point at which the member should be lifted to effect its separation from the male member.

. As will be.readilyapparent by reference to Figure .7 of the drawings, as the truck body is dumped the envelope will be lowered at =itsdischarge mouth end causing the weight of the cementto exert a forceupon the .fia'p 20 which will'caus'e the fastener members 30 and 31 to move. relatively in the manner necessary topermit them to separate automaticallyYand release thecement from theyenvelope, While the envelope is thus capable; of being automatically discharged of its contents upon dumping of thetruck withoutthe necessity of first manually manipulating theefiap securing devices, the securing devices will prevent any undesirable opening of the flaps suchas might'be occasioned by Wind orJsimilar influences.

i My flap equipment also enablesthe filling of the envelope in the novel manner illustratedin Figure 8 from which it will be observed that a'nozzle member 33 may be con nected to the discharge" hopper 34 and, at envelope loading time, inserted at one end of the envelope betweenthegflaps 21 and 19+- 20, orzintermediately between any adjacent pairof securing devices 2601- 31 and the flaps 19'-20--to direct the'cement into the'closed envelope without disturbing the previously secured flap fastening devices. In this manner the: envelopes maybe loadedgquickly and 'WlthOllt danger of the cement spilling out or flying about. a, :Fromthe'foregoing description, taken in connection with the accompanying drawings, .it-is thought that'thenovel details of construction, the-manner of use and the advan-' tages of my invention will be readily: apparent to those skilled-"in the fartwhih'the invention relat -What'I claimis:
